// Description...: A structure which is a set of other structures.
// Comments......: This class is a subclassed to cater for more
//                 specialized structure collections, e.g. rule sets,
//                 reduct sets and decision table sets.  This class
//                 would therefore be a strong candidate for
//                 templatization, if it hadn't been for the fact that
//                 the RSES library has to encapsulated in a special
//                 way, thus making direct templatization difficult
//                 in practice.
